My old Photoshop boss Kevin used to show a chart that nicely depicted the march of tools from simple & broad (think Clone Stamp) to sharp & purposeful (Healing Brush), smartly tailored to specific needs. I love to see how computer vision is helping to extend that arc, as demonstrated here:
Adobe says SkyReplace uses deep learning to automatically figure out the boundary lines between the sky and the rest of the shot (e.g. buildings and ground). It can then not only swap out the old sky and insert a completely new one, but it can adjust the rest of the photo to take on the same look and feel as the new sky, creating a more realistic look.
The N-up UI reminds me of Photoshop’s early-90’s Variations dialog. Maybe graphically, as well as politically, everything old is new again.
